Kafka wants to clean up kaiju, but not literally! Will a sudden metamorphosis stand in the way of his dream? 
With the highest kaiju-emergence rates in the world, Japan is no stranger to attack by deadly monsters. Enter the Japan Defense Force, a military organization tasked with the neutralization of kaiju. Kafka Hibino, a kaiju-corpse cleanup man, has always dreamed of joining the force. But when he gets another shot at achieving his childhood dream, he undergoes an unexpected transformation. How can he fight kaiju now that he's become one himself?! 
Kafka manages to fight off a humanoid kaiju, rescuing Iharu and Reno. But before he can change back to his human form, Kafka is spotted by Defense Force officers, and the neutralization unit--led by none other than Vice-Captain Hoshina himself--is dispatched to dispose of him. Can Kafka withstand his superior officer's attacks without revealing his true identity?!
